Sure. There are two points.
One is that whether or not there's precedent doesn't necessarily weaken or reduce the committee's opportunity to bring forward motions it deems fit.
Two is that a mandate letter does not supersede the Standing Orders. The Standing Orders are what actually govern Parliament. The Standing Orders do not preclude this. In fact, in numerous cases, they permit this committee to examine areas within its mandate that its members wish to bring forward.
That is what we have here. My ruling is that it is in order.
